Description

Technical Field

[0001] The utility model relates to the technical field of tunnel blasting, in particular to a drilling and charging device for tunnel blasting. Background Art

[0002] During the tunnel excavation process, most of the time, blasting construction is required first. Among them, rock drilling blasting construction is an important tunnel blasting construction method. When actually carrying out rock drilling blasting construction, it is often necessary to open multiple blast holes on the blasting surface, and then configure the explosive packages according to the pre-designed blasting parameters and put them into each blast hole, and then detonate them to complete the blasting construction.

[0003] Publication No. CN216448719U discloses a fast charging device for tunnel blasting. The device rotates a threaded rod, and the threaded rod drives a pressure plate upward through a threaded transmission with a threaded sleeve. The pressure plate slides upward along the axial direction of the adjusting rod until it rises to the top, and a proper amount of explosive is added through the feed pipe. Then, the feed pipe is blocked by a cover plate and a blocking plate, and then the threaded rod is rotated in the opposite direction to press the pressure plate downward to press the explosive. When charging the blasthole, the pipe sleeve is inserted into the blasthole. The staff applies downward pressure through a handle, and the handle drives the support plate close to the base. In the support mechanism, the support plate drives the movable rod to slide in the sleeve and compress the spring. The support plate drives the charge pipe to slide in the pipe sleeve and insert into the inside of the blasthole, which is convenient for flexible charging according to the depth of the blasthole, so that the loaded explosives are all located at the bottom of the blasthole, thereby improving the safety of use.

The deployment and coordination of personnel also requires time and energy, affecting work efficiency.
